BORIS CHATZKELEWITZ, OF ST. PETERSBURG, RUSSIA.

CIGARETTE-WRAPPER-CHARGING MACHINE.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed February 24, 1906. Serial No. 302,713.

To all whom it may concern:

Be it known that I, Boers CHATZKELEWITZ, a citizen of the Empire of Russia, residing at St. Petersburg, in the Empire of Russia, have invented certain new and useful Improvements in Oigarette-Wrapper-Gharging Machines; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to machines adapted to fill completed cigarette tubes, one by one, with tobacco.

The invention comprehends mechanism by which the machine is supplied with tobacco in the form of a uniform uninterrupted layer, mechanism which cuts off from the above mentioned layer of tobacco the quantity necessary for one cigarette and brings it into the stranding press, a stranding press for pressing and shaping the tobacco to be supplied to the suitably prepared wrapper, a plunger which pushes the tobacco strand when molded, out of the press into the tube, and means for trimming the ends of the finished cigarettes.

The object of the improvements is to so construct and combine the various parts as to produce a compact, durable and reliably working machine.

The essential features of the invention are illustrated in the accompanying drawings in which a con structional form of the improved machine is shown.

Figiu'e 1 shows the machine in side elevation. Fig. 2 shows the machine in plan. Fig. 3 is a vertical transverse section corresponding to the lines A, A and B, B of Figs. 1 and 2, respectively, and looking in the direction indicated by the arrow a (Fig. 1). Fig. 4 shows a portion of the feeding device in section. Fig. 5 is a cross section corresponding to the line O-O of Fig. 4. Fig. 6 shows the machine partly in end elevation, looking in the direction indicated by the arrow b (Fig. 1) and partly in section. Figs. 7 and 8 are detail views of the cigarette tube drum with the driving mechanism therefor and the conveyer belt for the completed cigarettes. Figs. 9, 10 and 11 are detail views of the scissor device and its driving mechanism. for clipping the ends of the cigarettes. Figs. 12 and 13 are views illustrating a modified arrangement of the slide with the two plunger-s which serve for the proper presentation of the empty cigarette tubes to the stranding press and of the filled tubes to the scissors which clip the end of the charged cigarette.

To the frame 1, of the machine, is secured a horizontal table 2. which is provided with downwardly extending brackets 3, in which a single driving shaft 4 of the machine is mounted. Upon this driving shaft are mounted a number of driving cams for actuating the different operative parts by means of levers, rods or the like. These driving cams are in the form of peripheral or face groove cams, eccentrics etc, according to requirements.

Feeding of the machine is performed by the mechanism now to be described and in the following Way: Tobacco from the stock thereof is laid by an attendant within a box or frame (Figs. 2, 3 and 6) upon an endless conveyer 5 which is stretched over drums 18 and 19 and is moved along by the rotation of the drum 18 in the direction of the arrows. The drum 19 is located immediately in front of a guide channel the top of which comprises a grid 9 and which is formed by vertical side walls 8 and a horizontal base plate 7 (Figs. 3, 4 and 5). At the mouth of the guide channel above the endless traveling conveyer 5 there is mounted in the side walls 8 a roller 6 the outer surface of which is not smooth but is preferably corrugated and which is rotated at the same angular velocity as that of the drum 18.

In order to enable the endless conveyer 5 to be stretched the axle of the drum 18 is mounted, upon lever arms 10 which can be adjusted about an axle 11 on the frame of the machine by means of set screws 12.

The drum 18 and the roller 6 are rotated by a slide bar 14 mounted in fixed guide eyes 13, (Figs. 2 and 8) and which is reciprocated through a link 15, and double armed lever 17 pivoted at 16, by an eccentric disk 21 fixed on the shaft 4. Through links 22 and 23, levers 24 and 25 respectively, pawls 26, 27 respectively and ratchet wheels 28, 29, the slide rod 14 at each complete stroke rotates thedrum 18 and roller 6 respectively through the same angle which is usually one that corresponds to several teeth of the ratchet wheel. in this way the tobacco is fed by the conveyer 5 in steps 11. 6., intermittently, towards the roller 6 which presses the tobacco somewhat.

From the conveyer 5 the tobacco passes onto the plate 7 upon which it is pushed forward, likewise in steps, by fingers 31 on a hub which is also rotated in steps facilitating this movement. The hub 80 is rotated in a step like manner by a ratchet wheel 30 Fig. 1, the pawl carrying lever 33 of which is pivoted to the upper end of the lever 25. At every complete stroke of the slide rod 14 the drum 18, roller 6 and hub 30 are rotated through the same angle, and the conveyer 5 is fed forward a corresponding amount. For the purpose of making this angle of rotation larger or smaller, according to requirements, the pawl carrying levers 24 and 25 are formed with elongated slots 34 for the pins of the links 22 and 23 respectively, so that the distance of the point of attachment of the links from the drum axes and consequently the amplitude of swing of the levers 24 and 25 can be varied.

A bar 35 which carries teeth forming a rake 32 for the tobacco layer (Figs. 4 and 5) is secured to a slide 36 mounted to slide in the suitably formed end of the slide-bar 14. This slide 36 is moved up and down in such a way that it remains in its lower position as long as the rake 32 is pushed forward by the slide-bar 14, while at the end of this forward movement the slide 36 is moved upward so that the rake, which is then located above the grid 9, can be drawn back by the retiring slide bar 14 without dragging the tobacco with it, the slide 36 being quickly moved downward again towards the end of this movement for such a distance that the teeth of the rake are pressed into the layer of tobacco so that when the next forward stroke of the slide bar 14 takes place a definite portion of tobacco is thereby severed from the stock and conveyed to the stranding press.

The stranding press (Figs. 1, 2, 3, 4) consists of a stationary jaw 37 formed with a semi-cylindrical furrow 38, a movable jaw 41 formed with a correspon ding semicylindrical furrow 39 and a blade 40. The movable jaw 41 is attached to a slide 42 movable upwardly and downwardly in a fixed guide 43. The slide 42 in the constructional form of the machine shown, is positively controlled, through an adjustable rod 45 connected to a lever arm 46 pivotally mounted at 47 which arm is actuated by a driving cam 48 having a suitably shaped annular groove 49 in its face. The movement of the rod 45 may, as will be seen from Figs. 1 and 3, by utilized to operate the slide 36, which carries the rake 32 in such a way that the slide 36 is raised on the descent of the rod. For this purpose a lever arm 50 is pivoted to the rod 45 through an intermediate link 51. Keyed upon the same spindle 53 as the lever arm 50 is a second lever arm 52 which moves the slide 36 through a link 54.

As soon as the portion of tobacco required for the filling of each cigarette tube has been conveyed to the stranding press, the latter is closed by the slide 42 with jaw 41 moving downwardly, the blade 40 cutting off the fibers projecting laterally from the press after which the movable jaw 41 is then immediately raised somewhat by a spring 44 which connects the movable jaw 41 with the guide 43. This movement of the jaw 41 under the action of the spring 44 is restricted to a scarcely noticeable extent by the suitably chosen form of the operating cam 48 and its annular groove 49, and its only object is to so release the compressed strand of tobacco that it can be easily pushed out of the press.

During the descent of the jaw 41 a cigarette tube is pushed and clamped fast by a device, hereafter more fully described, onto a usual form of mouth-piece 55 and into this cigarette tube the pressed strand of tobacco is thrust by a plunger 56 immediately the jaw 41 has retired somewhat. rette tube to the mouth-piece 55 takes place in a well known way by a cushion roller 57 (e. 9., an india-rubber roller) which is mounted on a lever arm 58 rocked through a lever-arm 59 by a cam disk 60 and thereby pressed against the mouth-piece form time to time as required. The plunger 56 is mounted on a slide 61 which is reciprocated by a drum 62 formed with spirally arranged peripheral groove 63, keyed upon the driving shaft 4 and a lever 65 pivotally mounted at 64 (Figs. 1 and 2), and having a roller working in said groove.

Behind the portions of the machine hereinbefore dedrum 66 by a spring 125.

The clamping fast of the ciga i plunger 56.

scribed is arranged a drum 66 which is loosely mounted upon a shaft 68 parallel with the plunger 56 and secured in a bearing bracket 69 (Figs. 68). This drum has furrows 67 in its periphery each of which can conveniently contain a cigarette tube and which is arranged to travel below and form the base of a magazine 70 the walls of which incline downwardly and in which there is always contained a stock of cigarette tubes. At each stroke of the machine, which corresponds to the filling of a cigarette tube, this drum is rotated one furrow so that in place of the filled cigarette tube, a new and empty one advances. This empty cigarette tube must be always so accurately presented that by moving it along the furrow, it can be pushed onto the mouthpiece hereinbefore mentioned.

For the stepwise rotation of the drum toothed wheel 4 gearing has always been hitherto employed, but such gearing (in view of the play of the engaging gear wheels) is liable to unavoidable shocks, joltings and consequent inaccurate presentation of the empty cigarette tubes. For the purpose of obviating these disadvantages, the rotation of the drum 66 in this machine is effected by means of a specially constructed and mounted lantern pinion 71, which gears directly into the furrow 67 of the drum. The lantern pinion employed is characterized by the fact that its round driving rods 73 have a covering 72 of elastic material and that their external diameter when covered corresponds to the breadth of the furrows in the drum which, conse quently, are entirely filled up by the covering of the rods which prevents any loss motion. To render smooth engagement of the lantern pinion with the drum possible under these circumstances, the pinion is mounted upon a frame 74, which can rotate about a pivot 75 in fixed bearings 76 and is pressed towards the (Figs. 6, 7). The lantern pinion 71 is rotated by a ratchet-wheel 77 the pawl 78 of which is mounted on a lever 79, which is pivotally connected through a link80 to a double armed bell crank lever 81, this latter is so actuated by a cam disk 82, on the main shaft 4, that the drum 66 is rotated one furrow at each complete rotation of the driving shaft. By the use of the lantern pinion gear the drum is not only rotated through the necessary angle, without shock and jolting but also, as the covered bars 73 are pressed into the furrows 67, the wheel is held fast during the whole period of rest in the correct position, which is of great importance for the proper working of the machine.

After the cigarette tube to be filled -has been presented in the correct position, i. e. in line with the mouth piece 55, it is pushed onto this mouth piece by a plunger 90 and held by the cushion roller 57 until the molded strand of tobacco has been completely thrust into the cigarette tube by the plunger 56, after which the cushion roller 57 is moved away from the mouth piece and the filled cigarette is pushed back along the furrow 67 into its former position by the same At the next instant the drum is rotated onward one furrow and the cycle of operations is repeated. The cigarettes have however after being charged with tobacco to be clipped at the ends. For this purpose they are held back in the furrows of the drum by an elastic shield 83 (Figs. 6, 7) and are thereby fed one at a time to a cutting device, 6. g. scissor blades, a third plunger 91 insuring the accurate presentation of the cigarettes to the blades 104 of the cutting device. The shield 83 is shown in section in Fig. 2 while in Fig. 1, for the sake of clearness, it is removed from the drum.

The plungers 90 and 91., are in the constructional form of machine, shown adjustable upon a common slide 84 (Figs. 1, 2, 6) which is reciprocated in a horizontal direction by a drum 95 through a double armed lever 93 pivotally mounted at 92 and a line 94. For the purpose of 'acccurately adjusting the plunger 91 which has to push forward the cigarette to be clipped, the plunger is passed freely through the arms 85 and 86 of the slide 84 and clamped in position therein by means of a clamping screw 87 carried by the nut 88 of a micrometer screw 89 which is pivotally mounted on the said arms of the slide, so that the plunger can be adjusted by rotating the micrometer screw 89.

Figs. 12 and 13 show a modified arrangement of connecting mechanism between the slide 84 and plunger 91, according to which the micrometer screw 100 is pivotally mounted in lugs 97 on the fixed guide 96 of the slide and can therefore be conveniently actuated while the machine is working. The plunger 91 is passed freely through a guide eye in one of the lugs 97 and is furnished with an adjustable stop 98, which by means of a spiral spring 99, attached at one end to the plunger and at its other end to the slide 84, is pressed against a projection 101 on the slide so that the plunger, on the return movement of the pusher, to the right, is pushed back by the projection 101, the spring 99 compclling it to follow the forward movement, to the left, until the stop 98 strikes against the nut 103 ofthe micrometer screw, which nut by rotation of the screw 100 can be conveniently adjusted at any time and the stroke of the plunger therefore adjusted or regulated according to the length of the cigarette desired.

A further improvement in the herein described machine is constituted by the construction of the mechanism for clipping the ends of the cigarettes. This cutting operation has been performed hitherto either by ordinary scissor devices or by revolving cutting disk. The fast do not work reliably, as the blades of the scissors cannot be brought together quickly enough and at the same time they tend to push the cigarette out of place or to push it out from between the blades. The cutting disks on the other hand work better, but are nevertheless not reliable inasmuch as they quickly wear out and become blunt due to the strong pressure with which they are forced against the counter blade.

In order to obviate the disadvantages of the ordinary scissors mentioned, an improved constructional form thereof shown in F 9, 10 and 11 is employed. The blades 104 of the scissors are interchangeably attached to lever arms 105 which are mounted upon separate shafts 100 and 107 adapted to rotate in the fixed guide piece 43. The blades 104 are actuated by roller furnished lever arms 11.0, 111. the rollers 108, 109 of which engage in grooves 112, 113 inclined to one another and formed in the pusher 114. This pusher is moved up and down in a guide frame 115 for example by an eccentric 1 lo on the shaft 4, eccentric strap 124, double armed lever 117 and a link 118. The eccentric and eccentric strap, may be replaced by a cam disk and a spring, which presses the lever 117 against such disk,

the latter being so formed that the blades 104 of the scissors are swung towards each other or closed as quickly as possible and move quickly apart again immediately.

For the purpose of obtaining a rapid movement, of the blades particularly from the instant when they come into contact with the cigarette, it is convenient, as shown in Fig 10 to form the grooves 112, 113 in the pusher 114 as cam or curved line groove or grooves the mutual angles of inclination of which vary. By mounting the blades 104 upon separate shafts 106, 107 the cigarette, if the blades be suitably shaped, is not pushed sideways during the cutting off of the tuft of tobacco sticking out of the wrapper (see Fig. 11):

Immediately the finished cigarettes have reached the lower edge of the shield 83 by further rotation of the drum 66 they fall out of the furrows 67 onto a conveyer belt 119 (Figs. 6, 7) which surrounds rollers 120 and 121 and is rythmically moved on in harmony with the work of the machine, for example, by means of a ratchet wheel 122, which is mounted on the shaft 121 and a pawl 123 pivoted to the lever 81 (Figs. 6, 7, S).
